Greek Columnar Basil

You probably won't be able to get any from anywhere, because it's a 'created' plant whose seeds will breed the original Greek basil. Best to buy a plant, and take cuttings from it now and then - that way, each plant will be a clone of its mother.

Just wanted to chime in here....I have Greek Columnar Basil, grown from a seedling. It's HUGE now, so beautiful. I love it. The smell is so aromatic. Very lemony, like sweet basil. It's a great plant.
One of my stalks broke off, and I took it indoors and put it in water, and before long roots sprouted, and after dipping in some root hormone, I transplanted it. It's doing really well inside the house.
This is a great basil.
